public class CharArrayWriter
extends Writer
This class implements a character buffer that can be used as an Writer. The buffer automatically grows when data is written to the stream. The data can be retrieved using toCharArray() and toString().

Variable Index

o buf
The buffer where data is stored.
o count
The number of chars in the buffer.

Constructor Index

o CharArrayWriter()
Creates a new CharArrayWriter.
o CharArrayWriter(int)
Creates a new CharArrayWriter with the specified initial size.

Method Index

o close()
Close the stream.
o flush()
Flush the stream.
o reset()
Resets the buffer so that you can use it again without throwing away the already allocated buffer.
o size()
Returns the current size of the buffer.
o toCharArray()
Returns a copy of the input data.
o toString()
Converts input data to a string.
o write(char[], int, int)
Writes characters to the buffer.
o write(int)
Writes a character to the buffer.
o write(String, int, int)
Write a portion of a string to the buffer.
o writeTo(Writer)
Writes the contents of the buffer to another character stream.

Variables

o buf 
Properties Inheritable 
   buf[]=char
The buffer where data is stored.

o count 
Properties Inheritable 
   count=int
The number of chars in the buffer.

Constructors

o CharArrayWriter 
    method CharArrayWriter() public
Creates a new CharArrayWriter.

o CharArrayWriter 
    method CharArrayWriter(initialSize=int) public
Creates a new CharArrayWriter with the specified initial size.

Methods

o write 
    method write(c=int)  public
Writes a character to the buffer.

Overrides:
write in class Writer
o write 
    method write(c=char[], -
                 off=int, -
                 len=int)  public
Writes characters to the buffer.

Parameters:
c - the data to be written
off - the start offset in the data
len - the number of chars that are written
Overrides:
write in class Writer
o write 
    method write(str=String, -
                 off=int, -
                 len=int)  public
Write a portion of a string to the buffer.

Parameters:
str - String to be written from
off - Offset from which to start reading characters
len - Number of characters to be written
Overrides:
write in class Writer
o writeTo 
    method writeTo(out=Writer)  public     Signals IOException
Writes the contents of the buffer to another character stream.

Parameters:
out - the output stream to write to
o reset 
    method reset()  public
Resets the buffer so that you can use it again without throwing away the already allocated buffer.

o toCharArray 
    method toCharArray() returns char[] public
Returns a copy of the input data.

o size 
    method size() returns int public
Returns the current size of the buffer.

o toString 
    method toString() returns String public
Converts input data to a string.

Returns:
the string.
Overrides:
toString in class Object
o flush 
    method flush()  public
